A point charge \(+q\) is placed at a distance \(d\) from an isolated conducting plane. The field at a point \(P\) on the other side of the plane is:
| 1. | directed perpendicular to the plane and away from the plane. |
| 2. | directed perpendicular to the plane but towards the plane. |
| 3. | directed radially away from the point charge. |
| 4. | directed radially towards the point charge. |

A hemisphere is uniformly charged positively. The electric field at a point on a diameter away from the centre is directed:
| 1. | perpendicular to the diameter. |
| 2. | parallel to the diameter. |
| 3. | at an angle tilted towards the diameter. |
| 4. | at an angle tilted away from the diameter. |

The electric field at a point is:
| (a) | always continuous. |
| (b) | continuous if there is no charge at that point. |
| (c) | discontinuous only if there is a negative charge at that point. |
| (d) | discontinuous if there is a charge at that point. |
